I have no sound on the ondemand plugin and it freezes the picture when i try to pause or rewind etc. I played the 1st few seconds of a couple of itv programmes and managed to get sound by turning on aac downmix and surround (?) downmix on. I then turned each off in turn to work out which was causing no sound. I left one on, I'm sorry I don't remember which one, then turned the other off and when I went to play another episode the box crashed. A recording was in progress at the time of the crash and restarted after but the box said no tuner available. I was able to search bouquets and go to a channel with no problem though. I only had one crash at this time but I had a hang with vix logo spinning earlier today which meant I had to turn the box off at power and restart to remove the hang. Any suggestions would be appreciated. Thanks.
